Liquor yeast is very important, which is also the reason why many research institutions at home and abroad study and cultivate it. At present, the commonly used cultivation method is induction method to select this excellent variety. PH value (pH value) and fermentation temperature. It is generally known that brewing is a chemical reaction, that is, starch is hydrolyzed by yeast fermentation to produce water alcohol (the main component of Baijiu) and carbon dioxide.

在适宜的温度和PH值下，酒曲中的微生物反应是活跃的，所以任何一种化学反应都有其利弊。在酿造过程中保持适当的温度和pH值，不仅可以加快白酒的酿造速度，还可以大大提高出酒率。PH值优于酸度，超过PH值，酒曲的活性下降，直失去活性。在该温度范围内，不能超过高温，否则会发生酿酒酵母的不可逆失活。

At appropriate temperatures and pH values, the microbial reactions in koji are active, so any chemical reaction has its advantages and disadvantages. Maintaining proper temperature and pH value during the brewing process can not only speed up the brewing of Baijiu, but also greatly increase the yield of liquor. The pH value is better than the acidity, and if it exceeds the pH value, the activity of koji decreases until it loses its activity. Within this temperature range, the high temperature should not be exceeded, otherwise irreversible inactivation of brewing yeast will occur.

另外，在发酵过程中，酵母不仅要产生葡萄酒，同时还要产生香气。此时只要控制好发酵条件，就能使香气物质和酒体达到平衡，使酒味醇厚，不挂口，香气扑鼻。总之，各种粮食的出酒率与酿酒酵母的种类发酵过程中的PH值温度氧含量密切相关。通过控制上述条件，可以酿造出白酒，提高经济效益。

In addition, during the fermentation process, yeast not only produces wine, but also aroma. At this point, as long as the fermentation conditions are well controlled, the aroma substances and body of the wine can reach a balance, making the taste of the wine mellow, not hanging in the mouth, and the aroma fragrant. In summary, the alcohol production rate of various grains is closely related to the pH value, temperature, and oxygen content during the fermentation process of the type of brewing yeast. By controlling the above conditions, high-quality Baijiu can be brewed and economic benefits can be improved.

那么在清洗酿酒设备的时分还应该留意哪些问题呢？

So what other issues should we pay attention to when cleaning brewing equipment?

当酿酒设备设备结束后进行水洗，用自来水冲刷糖化锅过滤槽堆积槽。冲刷发酵罐时，将自来水管路接在发酵罐排气阀上，排污阀翻开，冲刷10分钟。

After the brewing equipment is completed, wash it with water and use tap water to flush the filter tank and accumulation tank of the saccharification pot. When flushing the fermentation tank, connect the tap water pipeline to the fermentation tank exhaust valve, open the drain valve, and flush for 10 minutes.

进行火碱清洗。在糖化锅中参加自来水200L左右，再参加3%量的火碱片，进行加热，温度抵达80-90度。糖化锅过滤槽的碱洗经过糖化搅拌器过滤耕刀及饮料泵的输送来完结，发酵罐碱洗时，先将饮料泵换热器发酵罐排污阀之间管道链接起来，将火碱水泵入发酵罐，(留意!若火碱水溅到身上，应用大量清水冲刷，重者送医院就诊!)，然后用饮料泵将发酵罐中的碱液经过排污管与排气管进行循环，碱洗20分钟，再用泵将该发酵罐中的碱液经过排污管打入下一发酵罐，然后进行如上操作。

Perform caustic soda cleaning. Add about 200L of tap water to the saccharification pot, and then add 3% caustic soda flakes for heating until the temperature reaches 80-90 degrees. The alkaline washing of the filtration tank of the saccharification pot is completed through the transportation of the saccharification stirrer, filtration blade, and beverage pump. During the alkaline washing of the fermentation tank, the pipeline from the beverage pump to the heat exchanger to the fermentation tank drain valve is connected, and the caustic soda is pumped into the fermentation tank. (Pay attention to safety! If the caustic soda splashes onto the body, a large amount of clean water should be used to wash it, and in severe cases, the caustic soda in the fermentation tank should be sent to the hospital for treatment!). Then, the caustic soda in the fermentation tank should be circulated through the drain pipe and exhaust pipe using the beverage pump, Alkali wash for 20 minutes, then pump the alkaline solution from this fermentation tank into the next fermentation tank through the sewage pipe, and then proceed with the above operation.

发酵罐碱洗结束，可将碱液放入储存罐或稀释排放。假设清洗其它发酵罐时碱液温度下降的话，应从头回收到糖化锅从头加温再进行清洗。

After the alkaline washing of the fermentation tank is completed, the alkaline solution can be placed in the storage tank or diluted for discharge. If the temperature of the alkaline solution drops when cleaning other fermentation tanks, it should be recycled from the beginning to the saccharification pot and heated from the beginning before cleaning.

用热水清洗。在糖化锅中参加自来水足量，进行加热，温度抵达90-100度。糖化锅过滤槽及堆积槽的碱洗经过糖化搅拌机过滤耕刀及饮料泵的输送来完结。冲刷死角，需人工冲刷。发酵罐用热水清洗时，先将饮料泵换热器发酵罐排气阀之间的管路链接起来，翻开发酵罐的排污阀，冲刷5分钟。

Wash with hot water. Add sufficient tap water to the saccharification pot and heat it until the temperature reaches 90-100 degrees. The alkaline washing of the filtration tank and stacking tank of the saccharification pot is completed through the filtration of the saccharification mixer, the delivery of the plow blade, and the beverage pump. Scouring dead corners requires manual flushing. When cleaning the fermentation tank with hot water, first connect the pipeline from the beverage pump to the heat exchanger to the exhaust valve of the fermentation tank, flip the drain valve of the fermentation tank, and flush for 5 minutes.

后在运用前再用自来水(同上)冲刷即可。

Afterwards, rinse with tap water (as above) before use.
